  • The ion charge will differ depending on which group each element belongs to. Elements from the group 1A have a charge of +1 while elements from group 2A have a charge of +2. Transition metals are in the groups with a B with a number. Group 8A are the noble gases. Because they are very stable, they do not have a charge (no valance electrons).
  • The ‘ g ’ element is a container element for grouping together related graphics elements. A group of elements, as well as individual objects, can be given a name using the ‘ id ’ attribute. Named groups are needed for several purposes such as animation and re-usable objects. An example:
  • Group 1 (1A; the alkali metals) and Group 2 (2A; the alkaline earth metals) are referred to as s-block elements Group 1 elements have a noble gas core plus 1 valence electron with an ns 1 configuration.

  • The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Transition elements are those whose atoms have an incomplete d-subshell or whose cations have an incomplete d-subshell. Groups 13-18 termed p-block elements.
  • Periodic Table of Elements. Properties. Electrons. For elements with no stable isotopes, the mass number of the isotope with the longest half-life is in parentheses.
  • The atom of an element from Group 2A contains 2 electrons in the outermost shell. The atom can thus lose such two electrons to become a doubly-charged positive ion.
  • Group 1 Visible change, gas evolution and/or formation of a precipitate, with dilute hydrochloric acid. Ions of this group are carbonate, silicate, sulphide, sulphite, and thiosulphate. Group 2 The anions of this group do not react with hydrochloric acid, but form precipitates with barium ions in neutral medium. Ions of this group are sulphate,

Calcium is classified chemically as one of the alkaline earth elements (that is, in Group 2 of the periodic table. The metal is rather reactive. It readily forms a white coating of calcium nitride (Ca 3 N 2) in air. It reacts with water and the metal burns with a yellow-red flame, forming largely the nitride. Because Al is a main group element that lies above Fe, which is a transition element, it should be a more active metal than Fe. Thus the reaction should proceed to the right. In fact, this is the thermite reaction, which is so vigorous that it produces molten Fe and can be used for welding.

elements can e.g., R3P = O or R3P = CH2 (R = alkyl group). Phosphorus and arsenic can form dπππ–dπππ bond also with transition metals when their compounds like P(C2H5)3 and As(C6H5)3 act as ligands. (i) Reactivity towards hydrogen: All the elements of Group 15 form hydrides of the type EH3 where E = N, P, As, Sb or Bi.
